  • each key has a top surface, such as a flat top surface, that does not or substantially does not change its shape when the key is depressed similar to a conventional keyboard with individually depressible keys.
  • each key of the keyboard is displaced when pushed by the user of the keyboard, i.e. a key is depressed when activated by the user.
  • each key switch of the plurality of keys has a substantially non-flexible member with a contact element, and the non-flexible member is arranged to be displaced when the corresponding key is depressed until contact between the contact element and an electric circuit of the keyboard is established.

  • the keyboard is operated by a user in the same way as a conventional keyboard.
  • a specific type of tactile feed back experienced by the user during use of a particular conventional keyboard may also be provided by a keyboard according to the present invention.
  • the tactile feed back relates to how it feels to depress a key of the keyboard, for example whether a "click" is generated by a key when depressed by the user and how the "click" feels and sounds.
  • Tactile feed back also relates to the size of the linear displacement of the key when depressed by the user, etc.
  • the key switch is neither a dome switch nor a membrane switch.

  • an organic light emitting diode (OLED) display may reside on a flexible substrate, such as a very flexible metallic foil, a flexible polymeric foil, etc.
  • OLEDs can be printed onto flexible substrates in the same way as inks are sprayed onto paper during printing. Since OLEDs can be printed onto any suitable substrate using inkjet printer technology, they can theoretically have a significantly lower cost than LCDs or plasma displays.
  • An organic light-emitting diode (OLED) is a special type of light-emitting diode in which the emissive layer comprises a thin-film of certain organic compounds. Originally, small molecule organic light emitting diodes (SMOLED), i.e.

  • PLEDs have the major advantage of being solution processable, and can therefore be applied to substrates using techniques such as ink jet printing.
  • Dendrimer technology may also be applied in OLEDs.
  • Dendrimers is a class of molecules featuring a high degree of branching and which can be designed to offer specific performance characteristics. In particular, in display technologies, dendrimers can be applied to small molecules to give them some of the properties of polymer systems e.g. solution processability.
  • PMOLED passive matrix OLED
  • the cathode and anode are arranged in strips perpendicular to each other. The intersections of the cathode and anode make up the pixels where light is emitted.
  • External circuitry applies current to selected strips of anode and cathode, determining which pixels get turned on and which pixels remain off. Again, the brightness of each pixel is proportional to the amount of applied current.
  • PMOLEDs are most efficient for text and icons and are best suited for small screens (2 to 3 inch screens) such as screens for cell phones, PDAs and MP3 players, etc.
  • AMOLED Active-matrix OLED
  • the cathode and anode constitute full layers, but the anode layer overlays a thin film transistor (TFT) array that forms a matrix.
  • TFT array is the circuitry that determines which pixels get turned on to form an image.
  • AMOLEDs consume less power than PMOLEDs because the TFT array requires less power than external circuitry, so they are efficient for large displays.
  • AMOLEDs also have faster refresh rates suitable for video.
  • AMOLEDs are use in computer monitors, large screen TVs and electronic signs or billboards.
  • OLEDs do not require a backlight to function. This means that they draw far less power and, when powered from a battery, can operate longer on the same charge. It is also known that OLED based display devices can be more effectively manufactured than liquid-crystal and plasma displays.
  • OLED technology is currently used in commercial applications such as small screens for mobile phones and portable digital music players (MP3 players), car radios and digital cameras and also in high resolution micro-displays for head-mounted displays.
  • MP3 players portable digital music players
  • Such portable applications favor the high light output of OLEDs for readability in sunlight, combined with their low power drain.

Abstract

La présente invention porte sur un clavier présentant une pluralité de touches pourvues de commutateurs de touche recouverts par un dispositif d'affichage flexible permettant d'afficher des étiquettes individuelles des touches, permettant de changer l'étiquette par une commande appropriée du clavier pendant le fonctionnement du clavier. Le dispositif d'affichage flexible est pré-façonné en une forme non planaire pour s'ajuster sur le dessus des commutateurs de touche, de telle sorte que chaque commutateur de touche peut être activé par pression de la zone du dispositif d'affichage flexible affichant l'étiquette de touche du commutateur de touche en question. Chaque touche peut être munie d'un capuchon de touche à surface supérieure transparente sous lequel est monté le dispositif d'affichage flexible monté permettant d'afficher l'étiquette individuelle de la touche visualisable à travers la surface supérieure transparente du capuchon de touche. Le clavier fournit une rétroaction tactile analogue à un clavier haute qualité classique.
